Ok so when I fill my scar mags, shelled pants is right. I wait until I don't hear the mag filling. Make sure your filling correctly with a full tank otherwise you will have cycling problems and fps problems. Now back to the mags. Are you sure they are they are coming frome the valve? Are thwy leaking when out of the gun? If they are leaking out of the gun you should pull the core out of the casing and fill it up with gas then dunk it in water. It will tell you where exactly its leaking. I have had 2 leak from a sealed plate on the side and one I'm currently trying to fix is a crack on top under the feeding tip. If it is coming from the valve try tighting it up. A lot of times things get loose.
